How does it work?

The toilet with sink on top makes use of gravity to help conserve water. Every time you wash your hands, the water is then transferred onto the toilet for use. This way, every flush saves some water which accumulates into a big amount. The sink is placed on top of the toilet’s flush, where a thin tube is used to transfer water. The water you washed your hands with flows through the tube and gets ready to be flushed the next time you use the toilet.

Is the water clean?

Yes, the water being used is clean. The water is transferred to the toilet with sink on top smells better due to the soap being used beforehand for the hand wash. Moreover, the toilet water has germs and bacteria within; the soapy water keeps the germ transmission to a reduced level.

Remember to close the lid of the toilet while you’re washing your hands. This avoids the splashing of water when it is getting transferred.

The dual flush toilet has two buttons; one is for high volume flushing while the other one is for low volume ones. The solid wastes are flushed using the high setting while the liquid waste is flushed through the low setting. This ensures efficient flushing- no more than what is needed is being used.

How much water is needed?

On average, 5 to 7 gallons are needed per flush, while some dual flush toilets use up to 8 gallons on average per flush. The toilets made in a more modern setting use about 3.5 gallons on an average per flush. With that being said, dual flush toilets that have recently been invented use as low as 1.1 gallons per flush. This shows how the method promotes efficiency and saves quite a lot of gallons of water in each flush.

Which buttons to use?

The two flushing options- a dual and a lever button. Your toilet sink would include a manual with instructions; consult the manual every time you face confusion. Usually, the larger button is the high setting one, whereas the small one is for low. However, some designs might have equal sizes for both buttons, so the manual is required.
